Question about hosting

I use a third party for my domain name and a third party for hosting. Is it possible to condense these into my SquareSpace account and keep things more streamlined for myself? Thank you for any input.

You can move your domain to Squarespace and build a site here as well. Squarespace sites are not hosted outside of Squarespce like Wordpress can be. 

What you want to achieve is quite difficult. So it seems to me that it will have to pay even if it is possible based on this platform. Then it's a question of money. If you have it, everything will work out - if you have to find another way on the Internet. Personally, for my work, I found web hosting, which is easy enough to use. In general, now I do not use additional applications. Only if I want to upload some video and need extra processing. This might be a good solution for you as well. To find good hosting, you may need to read hostkoala reviews. Then you can decide whether it meets your requirements.
